Toshiba Won't Turn On

I have a Toshiba Satellite A130/A135 that was working just fine in the morning, but when I went to turn it on today, it wouldn't start. Holding the power button for a few minutes, switching batteries, nothing has worked so far. The only sign that it isn't completely dead is that the AC Power light is on, but nothing else. Any help would be much appreciated.

I am having this exact same problem too. Same model, everything. Was working fine this morning, shut it down properly, when I got home it wouldn't turn on. Only indicator is that the tiny blue AC adapter light is on, but none of the others.

The FN key does nothing.

The laptop is only 6 months old. It was plugged into a surge protector so that shouldn't be the problem.
